Hi,
What happen when exit system call is made from.
1) main () 2) task created with pthread_create.
I have written a same program as below which has a loop in main ().
When pthread_exit is uncommented. main is not exiting and running in
infinite loop.
but it halts when i comment pthread_exit. So, i would like to
understand what happens when exit is called and how does pthread_exit
is effecting the behavior.
void *PrintHello(void *threadid)
{
long tid;
tid = (long)threadid;
printf("Hello World! It's me, thread #%ld!\n", tid);
//pthread_exit(NULL);
exit(0);
}
int main (int argc, char *argv[])
{
pthread_t threads[NUM_THREADS];
int rc;
long t;
for(t=0; t<NUM_THREADS; t++){
printf("In main: creating thread %ld\n", t);
rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
if (rc){
printf("ERROR; return code from pthread_create() is %d\n", rc);
exit(-1);
}
}
while (1);
return 0;
}
